is this a bug or just a limitation ?
by Mariano Martinez Peck 01 Mar '09

01 Mar '09

I am inside a method and I do ctrl + s where I have a undeclared variable. In that moment, a popup appears and I want to do "declare temp" for example. But, as I did ctrl + s I would like to go to "declare temp" with the beyboard, and then, press enter. But this, doesn't work and the popup is closed. To make this work, I have to click on "declare temp" with the mouse :( I think the most important thing I miss for others IDE is the mouse dependence we have in squeak. Just as an example, when I use Eclipse, I almost don't need the mouse and it is very fast this. Thanks, Mariano

[Election] IMPORTANT: Voter list test mail
by Göran Krampe 01 Mar '09

01 Mar '09

Hi! Ok, the vote is coming up fast and I decided to test the voter list. We have a list of 461 voters. I just sent out a test mail with this subject line: "[Election] Test mail for upcoming vote" ...and got 32 bounces for the emails listed for the names at the end of this email. - If you ARE on the list of names I need for you to send me your correct current email address in order for you to receive your ballot. If you do not send me a new email address - you will not be able to vote. You can send me a new email address all up until the voting closes on 2009-03-08, just don't cut it TOO tight. :) - If you DID receive the email all is FINE. You will thus receive the real ballot when sent out on the 1st march, 18.00 UTC (ish). You can stop reading now. :) - If you did NOT receive the email, and you are NOT listed below, then you are NOT on the voter list. If you want to vote, send me an email *before 2009-03-01, 18.00 UTC*, and explain why you think you should be eligible to vote :). After 2009-03-01 the voter list will be FROZEN. - For more details on the election, see: http://wiki.squeak.org/squeak/6116 regards, Göran ---------------------------- Voters that bounced: Alan Lovejoy Alan Reider Andrew Catton Brian Pagano Cees de Groot Chao-Kuo Lin Chris Nelson Dany Daltman Doug Merritt Ed Jason Evan Dembskey Haruko Inoue Jan B.

Known bug with text editor and scroll ?
by Mariano Martinez Peck 28 Feb '09

28 Feb '09

Hi people: I am having a problem and I think is a known bug but I want to be sure. Sometimes, not very often, I have a method that is bigger (vertically speaking) than the editor inside the class browser. I mean, the whole method cannot be see in the edit but a vertical scroll appear. I want to select text, using shift and down narrow for example, and go to the end of the method. The scroll should move and the editor should show the end of the method, but it doesn't happen. The visible part of the method doesn't change. However, it does select all the text (the one is down, I can see it). Please, don't answer me "this is a feature. You must extract something to another method" because this is not ALWAYS true just sometimes. Thanks for the help, Mariano

[ANN] Hydra now can do mitosis
by Igor Stasenko 27 Feb '09

27 Feb '09

Hello lists, (see http://en.wikipedia.org/wiki/Cell_division for explanation what mitosis is ;) i just finished another torturing session in slang land, and finally made some of it working :) I added a two new primitives, which aimed towards creating a new heap by cloning a designated set of objects from existing one. A first primitive is helps you to create a closed graph by reporting a set of objects which is referenced by objects in provided array, but not included in this array itself. A second primitive is actually serves for creating a baby heap. I takes two array arguments: objects graph, and replacements (or substitutions). The rules is simple: each object included in first array, should have references to objects which included in this array as well i.e. (objects identityIncludes: (objects at: x) someIvar ) == true or if its not , then it can be found in a substitutions array. A substitutions array is a flat array of pairs oop -> index, where oop can be any oop, and index is a smallint index of item in objects array. Upon creation of new heap, all refs to oops in 'substitutions' array will be replaced by refs from 'objects' array by taking corresponding index. Both array arguments should contain oops only (except from indexes in substitutions array) , should not contain duplicates and their intersection should be empty , i.e. (objects intersection: substitutions) isEmpty == true. All of these rules actually serving to ensure that newly created object memory will form a fully closed graph (hence its oops can be cloned to a standalone object memory). There are also, an initial example how to create a 'baby' object memory load http://www.squeaksource.com/HydraVM/HydraVM-sig.17.mcz and do: HydraClone new cloneIdleProcess Of course you will need new VM. Sorry, i didn't published an update of sources yet. I can only give you a prebuilt one. Once i had a write access to ftp.squeak.org/HydraVM but i forgot credentials/key to it. (if Box Admins help me with this, i will upload it there). Or, you can write me in private and i will send you binaries. P.S. I want to give a credit to Klaus D. Witzel who helped me to finish these new features, and inspired to do it :) -- Best regards, Igor Stasenko AKA sig.

I heartily agree with all of that, but there's more to it, something which ought to inform our view of the SqC period and our expectations for time since then. Clearly, the most important thing is a pool of good people. We still have that. What Squeak Central had, and which we have rarely had since, is supported time. The financial support that SqC had from Apple and Disney was critical to its success. It provided them the time to do their work, and bolstered their authority when debate arose. Some of us have had time to contribute when between jobs, or when working for companies who tolerate our participation (e.g., when using Squeak as part of some larger development effort). Those are both useful, and we should use that time where we can. SqC had something more. They had support (while it lasted) for full-time development of the core system, as an open-source project. Dan himself is a great example of this. Just like most of us, he was too busy doing other paid work last year to participate in the leadership team as he would have liked. Of course, establishing an environment that allows something like SqC to prosper is the real trick. But we shouldn't forget how important it was in the history of this project. thanks, -C [1] http://tinyurl.com/cmz4x4 (lists.squeakfoundation.org)

That is behaviour that is independent of the issue. Css in Seaside FileLibraries is likely to have long methods. Stephan
